To all whom it may concern;

Be it known that l, Jenn ARCHIEBORLAND,.

a citizen of the United States, residing at Sit-afoul, in the county of Ramsey {incl citate of l /iinnesote have invented certain new and Demountable Rims which the foluseiful Improvements in for Automobile-Wheels, oi lowingis a specification.

This invention relates to clemountahle rims for automobile wheels and has for its object to provide a rim that he very quickly i'nountecl and (lemountecl.

Another object of the invention is to provide a. wheel rim having tongue and groove connection with v a Wheel.

A further object of the invention is to provide a novel locking connection between a. (lemountalole rim and Wheel.

With the above and such other objects as may hereinafter appear, I have invented the device illustrated in the accompanying drawihgs, in which embracing my invention.

Fig. 3 is a fragmentary plan view of e fellv.

Fig. e is e'section on line B-B- Fig. 2.

Fig. 5 is a fragmentary perspective view of e folly rim.

Fig. {3 is a sin iler view of a clemountable rim shown inverter Fig. 7 is a detail elevzitional lock member.

Fig. 8 is s, View similar to Fig. 4-. the members in a different position.

Fig. 9 is a detail elevational view of n the inflating valve used in connection with my invention.

Fig. 10 is another elevationel view thereof; and

Fig. 11 is an enlargecl longitudinal inental section of the rim ineni oers shown in locked relation.

Fig. 12 is an enlarged sectional View on line CC Fig. 1.

Like reference characters indicate like parts throughout the following specification and in the several viewsin the drawings, in which 1 is acommon automobile Wheel of view of a show in 5;

any desired or conventional type, having a.

folly 2 in which is provided a bayonet joint slot 8 alining Witlrn, similar slot in the folly rim 5 which is fixedly mounted upon the folly. This rim is provided with on out- Figure 1 is (D elevotional view of a wheel angular 8 on one is also PROVlQlfiil. pro} noting spaced turned. annular ri tie mnei edge there with a, series of outwardly apart lugs 7 end 8 with inclined Wells 9 and 10, in the former of Wil grooves 11, to receive the similarly iorineti tongues 12 projecting from the incline-5i Wells 1. of the lugs 15 on the inner surface 16 of the demounteble rim 1?. The grooves 11 extend into the hotly of the rim to form means to guide the tongues 12 into said grooves on the lugs '7. Alternating with lugs 15 on the rim 1? are lugs 1% which conform to lugs 8 on rim 5 and are adapted to seat thereupon. The outer surface of rim-1'? has its edges 19 and 20 curved inwardly to reccive the ribs of the tire 21. An annular inturned flange '22 is provided onsrim 17 Which may be formed by crimping the sheet metal from which the rims erepreierahly stamped. The flange '22 is on the outside of the rim. Fixed to the rim 1? is an apron '23 which is adapted. to forms closure for slot 3, the apron is provided with a tubular passage 24 through which the valve 25 projects. When the. rim 1? is mounted this valve 25 operates in the slot 3.

Mounted diametrically opposite the valve apron on the rim 1? is it look member 25 having an apron 27 to conform in appearance to apron The lock 26 consists of a bolt 28 operating; in the barrel '29 and. being pressed hv o. sp ing suicl holt having a stem 31 project opening in the head; 3:2 of the barrel which is pro- :itletl With e hand hol l he bolt me he oper V 2 st 1; new 1 of sp ring 30. The l v i ending through :1 slot 35 i to on r t by ri nr angular ex .znsion 0. ti ivlnrehy the bolt may helcl out in; position. When the rim. 1? is sli (l 1 t pl ee over fixed rim 5, the lugs 15 nil l8 in" l'lllP/[llend slight rotary ative to rim 5, thus securely locking theriin' 17 upon the Wheel. To demount se-icl rim 11 all that IS necessary is to (isew the bolt v movement relv "ch ere provioecl 28 against the tension of spring 3 0 until pin 34: may be rotated to seat on shoulder 36, after which rim is given a quick rotary movement as in 5, thus causing the lugs 15 and 7 to separate, whereupon the rim 17 may be readily removed.

It Will be noted that the flanges 6 and 22 of the rim members 5 and 17 are for the purpose of hiding the spaces 39 and 40 between the two rim members and the supporting lugs therein. The flange 6 (refer to Fig. 12) is spaced slightly apart from rim 17, as at 41, and the flange 22 is spaced slightly apart from the edge 42 of the rim 5, as at 43, in order to prevent any binding or sticking'together of these parts, leaving the rims to be easily separated. The method of disconnecting and demounting the rim 1? is so simple that it may be accomplished in six seconds time. The rim 17 may be stamped from sheet metal and will,'therefore, be ex-' tremely light and easy to handle besides very inexpensive, While at the same time it will meet all requirements as to durability and strength.

Having now described my invention that Which I claim as my invention is: f 1. In combination a Wheel the outer periphery of Which is provided with a series of spaced lugs having circumferentially bev- 1 eled surfaces, alternate lugs being provided with circumferentially extending grooves, a demountable rim provided with a COl'Ie-- sponding series of inwardly extending beveled lugs adapted to seat in the first mentioned lugs, alternate lugs thereof being provided with projections adapted tobe seated I in the grooves of the first series of lugs by I l 7 relative circumferential movement of the Wheel and rim and means to prevent retro grade movement of the rim.

2. A demountable rim formedof sheet metal having means on the'inner side thereof to secure it to a wheel in spaced relation and having at one side thereof an inwardly extending flange formed by crimping the material of the rim together the said flange having a thickness approximately double that of the rim.

3. In a wheel a fixed rim having a seriesof spacing lugs every alternate one of which has a smooth surface and the other alternate ones being provided with grooves and a demountable rim having coacting lugs every alternate one of which is provided with a. tongue to engage with said grooves to lock the demountable rim against lateral move-- ment.

4. In a wheel a fixed rim having a series of spacing lugs every alternate one of Which has a smooth surface and the other alternate ones being provided with grohves and a demountable rim having coacting lugs-every alternate one of Which is provided with a tongue to engage with said grooves to-lock the demountable rim against lateral movement said grooves extending into the body of said fixed rim to form guides for the tongues.-

In testimony whereof I afiix my signature in the presence of two Witnesses.
